GO5 - Operation Planning and Control

Image
  Grid Operation Part 5 Operation Planning and Control Better Start With PART-1 Power system operation planning is done on the previous day for implementing it on the next day. All required data like forecasted load, generation availability, network status, etc are collected along with schedule changes. Operation planning, monitoring and control is a continuous task because operation planning has to be modified in real-time to accommodate unexpected changes in generation, demand, network, etc. Power system operation planning and control is based on three fundamental criteria 1.       1 .      System security. System security remains a top priority while system operation planning, monitoring, and control. Therefore any occurrences that jeopardize system security are set right immediately by suitable measures. Practically 100% security cannot be guaranteed but the security level has to be enough that changes of major occurrence are little...

GO4 - Asyn Interconnection

Image
Grid Operation Part 4 System Interconnection Asynchronous Better Start With PART-1 Synchronous grids were developed up to regional level. There were five regional grids WR, ER, NR, SR and NER. National grid was envisaged with following advantages. Our country is wide spread from Kashmir in north to Kanyakumari in south and from Kutchh in west to Arunachal in east with variety of culture, festivals, weather and time zones. There is diversity in power demand due time zones from east to west and temperature zones from north to south during seasons and time of the day. Northern area is hilly having more hydro resources. Maximum hydro power is available during post winter period because of flood in rivers due to melting of ice. Availability of hydro power in other areas may be during monsoon.   Thermal generation is also effected due to local seasonal issues. Coal stacked in open yard gets wet and lumpy in monsoon due to rain. Generation drops due to problems in grindi...
